Answer:
75
Step-by-step explanation:
Jim will finish in 6 days because 300/50=6
So you know that Sam needs to finish the book in at exactly 4 days
300/4= 75 pages per day
Answer:
-1/2
Step-by-step explanation:
The equation for slope is (y2-y1)/(x2-x1).
Plug in the values given in the problem
(11-7)/((-2)-6)
Then simplify
4/(-8)=-1/2
The intensity of sound which the decibel level of the sound measures 156 is 3.981 × 10³ W/m²
Decibel level, dB = 10log₁₀(I/I₀) where dB = decibel level = 156, I = intensity at 156 dB and I₀ = 10⁻¹² W/m².
Since we require I, making I subject of the formula, we have
dB/10 = log₁₀(I/I₀)

Substituting the values of the variables into the equation, we have

I = 3981.072W/m²
I = 3.981 × 10³ W/m²
So, the intensity of sound which the decibel level of the sound measures 156 is 3.981 × 10³ W/m²
